The middleweight fight was a rematch from their eight round split decision draw that occurred exactly three months ago.

Alvarez, who is an older brother of Canelo Alvarez, left very little bout this time around against the gatekeeper Navarette. Alvarez (25-6-3, 16 knockouts) was the busier and more accurate fighter of the two, connecting with right hands to the head of Navarette.

Scores were 97-93, 98-92, and 99-91 for the 31-year-old Alvarez. The victory comes after Alvarez only won once in four bouts.

Alarcon won the WBO female flyweight title from Nana Yoshikawa in her previous fight on Apr. 29. The title was not on the line Saturday night.

Martinez (17-16, 9 KOs) came to fight and found some success during the middle rounds, but Alarcon landed the more effective punches, countering and mixing her attack to the head and body.

Scores were 78-74, 78-74, and 79-73 for Alarcon, who has won her last three bouts.

Zanfer Promotions promoted the card, which also aired on Azteca TV throughout Mexico.
